From 3dee43930fb48a0746621c99d46318aad8169980 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Mon, 6 Feb 2012 12:47:56 +0200 Subject: [PATCH] wl12xx: enter forced-psm on fw change Enter forced psm when changing fw, in order to make the sta a bit more disconnection-persistent. (DPM doesn't know about the incoming recovery, so it won't enter psm by itself) Signed-off-by: Eliad Peller Signed-off-by: Luciano Coelho --- drivers/net/wireless/wl12xx/main.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/drivers/net/wireless/wl12xx/main.c b/drivers/net/wireless/wl12xx/main.c index b3b4c401978..10c1ecdf9ba 100644 --- a/drivers/net/wireless/wl12xx/main.c +++ b/drivers/net/wireless/wl12xx/main.c @@ -2150,6 +2150,19 @@ static bool wl12xx_need_fw_change(struct wl1271 *wl, return false; } +/* + * Enter "forced psm".
